During this time, spacer 9 fell over and LCD 3
The mounting process becomes complicated, and the substrate 7 may be mounted on the top panel 1 while the LCD 3 remains in an unstable state.

In view of these points, the purpose of the present invention is to ensure that an LCD can be attached to equipment such as a telephone, and to simplify the process of attaching the LCD to reduce costs.

[Means to solve the problem]

The mounting structure of the liquid crystal display of the present invention is as shown in FIGS. 1 and 2, for example, as shown in FIG. 1 and FIG. Part of it is supported by 10H.

[Effect]

According to the present invention, the LCD support portion 10H integrally formed with the rubber sheet 10 supports the LCD.
Since the other end of the rubber sheet 10 is held, the support part 10H does not fall down, making it easy to mount the LCD 3.
Since it is 0H, there is no need to take the trouble to provide a support member.

〔Example〕

Hereinafter, one embodiment of the mounting structure for the liquid crystal display of the present invention will be described with reference to FIGS. 1 and 2.

10 is a rubber sheet made of insulating resin, for example silicone rubber. This rubber sheet 10 has a planar flat part 10F disposed facing the keyboard 2 of the top panel 1, and an LCD extending perpendicularly to the flat part 10F in a direction facing the end of the LCD 3.
It is formed integrally with the support portion 10H. In the case of this embodiment, a plate-like portion is formed over the entire one end portion of the flat portion 10F, and this is connected to the LCD support portion 1.
It is set as 0H. Therefore, the rubber sheet 10 has an L-shape as a whole.

Rubber switch portions 10s are formed on the flat surface portion 10F at positions corresponding to each operation button 2k of the keyboard 2. This rubber switch part 1
0s has a bowl-shaped shape that protrudes from the operation button 2k and is recessed from the printed circuit board 7. A movable contact is formed in the recessed portion of the rubber switch portion 10s.

Next, the procedure for attaching the LCD 3 to the top panel 1 will be explained below.

First, the LCD 3 is the liquid crystal display window 5 of the top panel 1.
, that is, between the walls 1a and 1b provided on the top panel, and then the LCD 3
The rubber connector 8 is inserted and arranged inside the wall 1a, that is, on the side where the wall 1a faces the wall 1b, so as to contact the electrical contact portion 3c, which is one end of the rubber connector 8. Next, the rubber switch part 10s formed on the flat part 10F of the rubber sheet 10 is placed at a position corresponding to each operation button 2k of the keyboard 2, and at the same time, the LCD support part 10H supports the other end of the LCD 3. Then, it is inserted and arranged inside the wall 1b, that is, on the side where the wall 1b faces the wall 1a.

At this time, the LCD support part 10H is attached to the rubber sheet 10.
